I decided to build a flying gantry router, X600 Y300 Z100.
It has 4 x Nema 23 motors 1.86nm holding, 10mm od Ballscrew with 3mm pitch, Fully supported THK linear bearings on all axis. I use the machine with a Trend Router for milling Delrin and Aluminium plate upto 10mm thick.
I also mount a laser I built from a DVD burner diode to etch plastics and organic materials pictured below.
